“It’s actually the opposite for women; if you have sex it raises your testosterone,” she explained during an interview with Conan O’Brien last year. “So it kind of sucks that I don’t have a boyfriend right now, but I’m sure my Twitter’s blowing up with offers.”

“For girls it raises your testosterone, so I try to have as much sex as possible before I fight actually. Not with like everybody, I don’t put out like a Craigslist ads or anything, but if I got a steady I’m going to be like, ‘Yo, fight time’s coming up,’” Rousey said.

Yes, so Ronda Rousey, the best female MMA fighter in the world, says she tries to have as much sex as possible before fights because it raises her testosterone. She has medical science on her side, and you can’t mess with that.

The only question is who is Rousey’s steady at the moment? We know she’s been busy filming movies. For her sake, hopefully she’s been able to find a partner … not that that should be very difficult for her. When she gets in the octagon, she definitely has the aggression of someone who’s had a testosterone boost.
